When I was about 10, I broke my first skateboard by riding it into a ditch. A decade later, in college, I broke another skateboard within an hour of owning it (surely a record) in a short-lived attempt at doing an ollie. (Surprisingly, the store accepted a return on that board even though it was in two pieces.) Then I was gifted a really nice, high-quality skateboard. The first thing I did with it was ride it down a big hill, a valiant but ill-fated adventure which ended with me jumping off the skateboard, rolling down the grass, and arriving scraped up, deflated, and rather disoriented near the entrance to my college cafeteria. (In my defense, the wheels and ball-bearings on that skateboard had been pre-lubricated to minimize friction, and why would anyone do that, that's just crazy.)
Level out on the way down – Before you start to head back towards the safety of the earth, level your feet out as the board begins to fall. If you’re trying to jump a gap on your board, this will help you keep going straight and maintain your momentum. Alternatively, you can land on your nose or tail and perform a manual out of the jump, but those are pretty advanced moves. Might want to wait until those little pink training wheels are off your board first.
If a skateboard deck is turned over to its design side, there are two complete T-shaped pieces of metal. This piece is attached to the skateboard deck with screws. The pin is a long piece of metal that is designed to turn the skateboard deck. Adjusting its tension affects the skateboard deck's turning sensitivity. Typically, longboards have looser tension than other skateboards to allow deeper turns.
To get higher ollies, I would suggesting resting your back foot on the very end of the tail and the front foot in the middle of the deck to allow for more slide. Popping as hard as you can and catching your board in the groove of the nose with you ankle practically resting in the groove will level the board out in the air. after this initial movement slide you feet back to the bolts on the tail and nose to ensure a clean landing.
